1 Each output is capable of delivering full output power, Po nom according to table: Model Selection.
2 The current limit is primary side controlled.
3 Measured with both outputs connected in parallel.
4 Conditions for specified output. Other output loaded with constant current Io = 0.5 Io nom.
5 BW = 20 MHz
6 Measured with a probe according to EN 61204.
7 The overvoltage protection is not tracking with the R control.
